E. SEASHOLTZ ADJUS TABIE SIDE BEARING Filed July 9, 1929 y?? Jr@ ATTORNEY Patented May 2o, 1930 UNITED STATES y EMonY'sEAsHoL'rz, or WAYcRos's, GEORGIA" ADJUSTABLE SIDE :BEARING Application led July 9,

My present invention has reference to a side bearing for thev trucks of freight or y other cars and has for its object to simplify and improve the construction of such devices by producing a bearing which will drop by gravity into the box therefor, rest upon a shim inserted in the box and will be thereby eiiectively retained in its box regardless of the vibration or even derailment of the truck, and 1c further one which may be easily andquickly adjusted to take up side bearing clearance without removing the same from its box, but which at the same time may be easily and quickly removed should occasion require.

A still further object is the provision of a bearing for this purpose which may be adjusted more easily and expeditiously and consequently with less expense than is required by the ordinarytype of such devices 2G and further wherein such adjustment is obtained without removing any of the bolts, rivets or securing means of the improvement.

The invention will-be fully and comprehensively understood from a consideration of the following detailed description-when read in connection with, the accompanying drawings which form part -of the application, with the understanding, however, that V the improvement is capable of extended apes plication and is not confined to the exact showing of the drawings nor to the precise construction described'and, therefore, such changes and modications may be made therefrom as do not affect the spirit of the invention nor exceed the scopel thereof as expressed inthe appended claims.

In the drawings: Figure l is a plan view of my-.improvement.

Figure 2 is a sectional view taken aproximately on the line 2-2 of Figure 1. y

Figure 3 is an end view of the improvement.

- Before entering into the details of my construction I think it necessary to state that with the ordinary devices for a similar purpose the bearings which are secured by four rivets must have their rivets cut off when the bearing is to be adjusted, so that shims may be arranged beneath the bearing. YThis 192:9. Serial No. 376,969.

is not onlyan expensive but laborious operation, as 1t requires about two hours time and generally three hands in performing the` same. VIn addition to this the new rivets' employed must be heated before the'same' can beheaded, and the cost of adjusting bear-` ings is estimated by the railroads at three dollars per car. It will be noted asthe description progresses that with my improve-A ment the bearing can be adjusted by asingle band, that such adjustment may be attained Withoutremoving the bearing from its box, and further that the'said bearing can beadj usted in approximately tenmin-utes and further that such adjustment can be obtained at a minimum costfor expense. y As disclosed by theY drawings my improvement contemplates the employment of a substantially rectangular box, l. Each of the boxes has its corner, at its lower end formed with an outwardly directed vear 2 through' which ear there are passed the rivets or like securing means that 'hold the box on the truck or bolster. When the box is once positioned itrmay not be removed; The box has its ends, adjacent to its bottom wall' provided with y substantially rectangular openings 3. These openings'serve a two-fold purpose, thatof inserting the shim whichv lis received between the bearing to elevate the said bearing and prevent the same .from acci- Y dental movement from the box as well as means for draining water out of the box.k Above'the opening 3 on one or both ends of the box the said end is formed withl a transverse slot 4, the said slot beingof a, length equal'ling that of a box between thev sides thereof. j v A The sides of the box, onA the inner faces thereof and adjacent the end provided with. the slot 4 is 'formed with a downwardly and inwardly directed curved groove 5,.and eachv *ofsaid grooves 5 merges into an upwardly directed substantially rectangular depression formed, ,of course,'upon the inner faces `of v the side walls' of the box. l I

The roller vbearing is substantiallyV elliptical in'cross section or more strictly Speaking the'same is substantially pear-'shaped in side elevation'. 'The relier bearing 7 has its Sides 2idY ' ings 3 a shim 9. This shim is preferably constructed of some cheapmetal, suchl for instanceasa boiler sheetandlthesaid. shim isV of athiekfnesssuflicient to .elevate -the roller bearing l,7 'to bringthe pins or trunnions theres of'in'line of 'Contact with the walls between the,k vertical' rectangular depressions jor.
